JACOB LIPS, or lvrnnnn-unnonr, SWITZERLAND,

GEABING.

To all'whom it may concern Be it known that I, J ACOB Lrrs,manufacturer, a citizen of the Swiss Confederation, residing atNieder-Urdorf, Canton Zurich, Switzerland, have inventednew and usefulImprovements in Gearing, of which the following is a specification.

The object of the invention is to provide an improved mixing andkneading machine, principally intended for mixing flour and water andkneading the dough.

According to the invention two kneading U implements, rotatablymountedon crank pins in a manner which is not in itself novel,

are provided with arms, and these arms,

placed crosswise, are connected by links to a fixed stud, by which partof the stress due to the kneading operation is borne.

The invention is illustrated in the accompanying drawings showing oneform of con- I struction,

Figure 1 being'a vertical section, Fig. 2 a front View, and Fig. '3 ahorizontal section on the line A-B of Fig. 1, p

Figs. 4 and 5 are detail views of the machine. 1

In the drawings 1 designates the frame, in which are mounted twoparallel, horizontal shafts 2 and 3, each carrying a gear wheel 4. Thewheels 4 are meshed with each other, and one of them is driven by a gearwheel 5. Each wheel 4 has a crank pin 6, upon which is rotatably mounteda sleeve 7 of a kneading 1 head, having an arm. 8. The arms '8 crosseach other and are both connected by links 9 to a stud 10 fixed to apart 11 of the frame. Each kneader also has a lmeading arm 12 fittinginto a groove in the kneader I head and having a kind of hook 13 at thetop, engaging over the partj1-5 of the head.

A pin 14 passes through the head and the arm 12, and is made fast bymeans of a catch 15 Axial movement ofthe 'kneaderon the crank pin 7 isprevented by a nut and washer Specification of Letters Patent. 1Application filed November 28, 1916. s rial No. 133,889.

16. The pan 18 is mounted by means of a I pivot 17 on a carriage 19having a table 20,- on which are two studs 21. Upon the frame 1there'are two pivots 22 for eccentric abut- Inents 23 having handles24.These abutments lie in the path of the studs 21 when the carriagewiththe bowl is moved to and from the machine, and they are so placed inrelation tothe studs that they can only be rotated into position toretain the carriage when the bowl is'in the" proper position 'inrelation to the kneaders.

tated by, means of'bevel gear. Whenthe wheels 4 are driven the kneadersrotate with the crank pins 6, and the stress 0 1 due to the work is inpart borne by the stud 10. When'the stress is greatest the parts arepositioned most favorably to bear it,'so that a strong machine can beconstructed of. comparatively light design.

Having now particularly described and ascertained'the nature of my saidinvention, and in what manner the 'same is to be performed, Ideclarethat what I claim is In combination, a frame, a; pair of parallel 7shafts mounted in the frame, a gear wheel mounted on each shaft, saidgears being in meshing relation, a crank pin extending from each gearwheel, a shaft disposed above and in a central plane between theparallel 7 1 shafts, arms pivoted on the crank pins and extendedupwardly and across each other, a link pivotally, connected tothe upper;end of each arm, said links being pivotally support- 7 ed upon thecentrally disposed shaft above 3 the gear'wheels, means for rotatingoneof .the gear wheels, and rods mounted on the crank pins and actuatedthereby. 1

In testimony whereof I aifix my signature in presence of two witnesses.
